Secure erasing files - at the vmdk level?

Hi all

We are implementing a corporate secure deletion policy by which our support staff will use a Windows tool that supports at least US DOD 5200, 28 - STD file deletion (all reasonably simple), but he was asked if the erasure spreads through to the underlying disk to VMware and if so, is the data stored in the disk correctly deleted also?

Our file servers are W2K3 and have HBA connections with our without.  VMWare "disks" are stored in hard (s) on the SAN.

Your comments and advice are appreciated.

Hello

Moved to forum security and compliance.

If your VMDK is stored on a storage that does not "copy-on-write", then it is possible to run a wipe program DoD disk in the virtual machine to zero level the VMDK. However, this may not work if you do not fully understand the underlying storage.

For linked clones, this will erase the link but will not erase the captain VMDK. Or this will remove any file .vswp, .vmsn, or .vmss files. These have images memory and therefore should also be properly deleted. If its not simple to delete a virtual machine to the DoD standards. Data disc are fine but the memory data is a little more difficult.

  • 4.1.1 fusion erases files on the Mac desktop that are deleted in Fusion

    I have merge 4.1.1 installed on a MacBook Pro with Mac OS X 10.6.8.  If I download a file on the Mac desktop and then drag and drop it on the desktop of Windows XP which runs under Fusion, a box of "copy" just stating that the file is copied to the virtual machine.  If the file is 95MB, for example, copy the area shows the progress of the 95MB copy to the VM.  So far so good.  At the same time, a file is created on the Mac desktop which is a duplicate of the file slipped to the virtual operating system of Windows.  If I trash the file on the Mac desktop, it removes the file on the Windows desktop as well.  I-mode installation of VMware Fusion full screen and have a second monitor on the Mac, where I've been the VMware virtual machine.

    It's as if the file on the desktop Mac was in fact the only real file and one on the virtual machine has been a 'shortcut' or 'alias' in the file.  Not sure if I just something I have to change in the settings of merger to prevent this, or if this is normal behavior.

    It seems that you have enabled the functionality of records at the Office for this Virtual Machine VMware Fusion mirror.  Check the settings of records in reverse in the Virtual Machine settings and uncheck the box office under folders in reverse.

  • I need secure erase for PX3012E-1HJ0 SSHD

    Sorry for posting my question here, but the Forum gives me '403 response Code' when I try to create a new thread, despite I have all the necessary rights

    Nice day! I bought two hybrid hard disks SSHD PX3012E-1HJ0 - http://www.toshiba.co.uk/hard-drives.../px3012e-1hj0/
    After some time of use I would sell a PX3012E-1HJ0 hybrid propulsion system to other people. But this is a problem: I have worked with important financial documents on this drive, so I need to ensure erase everything on the drive before selling. Of course, I know how to secure erase 1 TB main "Memory disk" of this hybrid propulsion system. But I don't know how to clear the cache of its ' 8 GB NAND "Memory SSD"

    Site Web de Toshiba tells that 8 GB memory NAND of player in SSHD retain frequently used data to self-learning algorithm of cache - http://toshiba.semicon-storage.com/e...q/storage.html

    I'm worried that there could be a cache of my important documents inside this 'SSD memory' so someone could use engineering tools for the extraction of my documents directly from him. I would like to secure erase or reset this cache, to return the SSHD command to his "immaculate condition retail

    Please tell me, how secure erase or reset the cache that is inside of 8 GB of memory NAND?

    As far as I know that Toshiba provides no special tools to perform these secure data erasure, but I recommend you to check the 3rd parts software called "Parted Magic".

    Parted Magic contains small tools such as Partition Image, TestDisk, parted, fdisk, sfdisk and ddrescue
    Just burn to a cable USB thumb drive (or CD), start on the USB, and once you get on the desktop, check the icon marked "erase the drive.

    Secure erase will return you an SSD for empty, fresh-out-of-the-box condition.

  • HP Probook 4530 s: how much time disk disinfectant and will secure erase?

    I have HP probook 4530 s ci5

    have a 750 GB hard drive (HDD) drive.

    Hard drive is Hitachi (HTS727575A9E364)

    I need my laptop to someone for a few days, so I need to make sure that my data is definitely missing.

    I can use the disk Sanitizer or present secure erase option in the BIOS. But I don't know how long it will take?

    Can someone please tell me which disk-disinfectant time and secure erase option will take to a passage?

    Hi all

    I just went ahead and did it. So for other people like me looking for the answer to this question, I will share my experience.

    When I clicked on the option of disk Sanitizer, he gave me several choices like, 1 pass, optimum, gutmen and custom. I chose optimum, it is has had warned only that data will be permanently erased, there was no estimate of the time, I had to do, I did. After 22-23 hours of waiting, he did. And the optimum had 6 cycles of option. He showed the result below.

  • How can I transfer a file from the operating system to a backup of the production running VM virtual machine?

    Problem:  After I do a backup one using ghettoVCB on a local VMFS volume, I have a virtual machine that I can start something happened to that running.  However, sometimes I just need a file from the OS level, which means that I would need to start to get them, but then I have an IP address conflict.  I can't imagine a way to have the NICs turned off and still be able to move the file.  If I change the IP addresses, the software that I need to create the file that I need to transfer no longer works because, although there no need of constant connectivity to the seller, it is locked to the public IP address.http://communities.vmware.com/images/emoticons/sad.gif

    Material:  I have two 4 ESXi hosts to work, each with local VMFS volumes.  They share a private vlan common and a vlan common public.  They each ssh, ftp, wput, wget, and rsync available.  I have a Windows 2003 Server VM which also hosts a NFS and the VI client and other VMWare tools.  It also has private and public interfaces as do virtual machines that would be to make and receive the OS files.

    Question:  How can I transfer a file from the operating system to a backup of the production running VM virtual machine?

    Thank you!

    Yes Mr President, make sure you set the network on this virtual machine to be connected to the 'Internal' vswitch, you set up before turning the power on to the virtual machine.

    What you need to do before anything else, it's everything and nothing important to you and to the stability of the machine (your ability to rebuild from scratch) backup because chances are - you will be rebuilding this computer from scratch and everything on this hard drive will be erased.

  • What level of security is the best in the OSI model, which is the application level?

    Hello

    I'm curious to know what level of the model OSI protects best against pirates, which is the application level?

    Thank you

    Johan

    Hello Johan,.

    The OSI networking reference model (ISO 7498 - 1) is designed around seven layers arranged in a stack.

    The OSI security reference model architecture (ISO 7498-2) is also designed around seven layers, reflecting a high level of different requirements in the security of the network.

    In the OSI model, each layer has its own functionality and according to which it has features of different security as shown below.

    Application - authentication

    Presentation - access control

    Session - non-repudiation

    Transport - the integrity of the data

    Network - Privacy

    Data binding - insurance / availability

    Physics - certification / Signature

    Sorting all of the drive is not possible. Perhaps, it can be done by another program I'm not aware of.
